Just moved into my new place so I gotta let the tomes of old out. This is the oldest I've had yet, by about a decade.
Oxidation has set in but in a very good way. It has transformed into a tart candied apple flavor. I've only had lambics this old and like them this definitely shows me of how a beer can age gracefully even with oxidation. Carbonation is still there and cork came out with ease.
This is so freaking good and drinkable, good thing this was the last bottle on etre or I would be buying the rest tonight!
